"After a supply line failure soaked our kitchen and part of the living room, COS Water Damage Restoration was at our Renner home in under an hour. The crew's moisture mapping caught wet wall cavity areas I never would have known about. Five days of drying, a perfectly documented insurance file, and zero mold issues. Exactly what you want from a restoration company."
